i used my juki on a frame for years. after rolling a large quilt, you only have 3.5-4" for quilting depth. i did do a king sized quilt with it and was able to quilt 12" blocks by creatively breaking down the pattern. so it took4 or 5 passes sometimes to quilt that size block. before i moved from MN, i sold my set up and am happy to say that i bought a 17" baily that i'm waiting to arrive. best wishes with your new machine.
